Calling/called  procs

There are 3 ways to see the chain of all the calling/called procs.

1/ In thread tab

2/ Backtracking (see context menu in proc/var tab and thread tab) : only the previous, current and next procs are listed.
Click on a button (Prev/Current or Next) to navigate in the chain of procs.

3/ Calling chain (see context menu in proc/var tab and thread tab) : all the procs for a thread are listed.
Click anywhere on one line to navigate in the chain of procs : the calling line is highlighted in source code and the proc is selected in proc/var tab.

Only one option could be used at the same time and the dialog box is canceled by any execution (step, run, etc) .
